You need to lower the sync speed by catting a value into
/sys/block/md{n}/md/sync_speed_max
the value should be about 1/3 lower than the max speed you see (cat
/proc/mdstat) now that it's not yet limited.
Set up a script to set it at boot.
If it was not happening for you on older kernels might be a good sign:
it might mean that the resync is faster now...
What is the sync speed you see (cat /proc/mdstat)? How many drives do
you have and what type of raid is that?
